Being able to pay to bypass TSA or cut the line for TSA has always been a thing. Private jets, Precheck, and this monstrosity where you pay a private company to become a more equal member of US society:
I'm not sure it's ALWAYS been a thing, or at least it's scale has definitely grown more recently, but, yeah, that's why I thought of it being extended to 'those with e-wallets', of course.
I do won't do any of that "clear" or even "pre-check" stuff just on principle; most everyone I know thinks I'm crazy. I try to fly as little as I can these days, even before pandemic, it's just so unpleasant both in terms of security/dignity as well as physical comfort.
